Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an adjacent marker supporting structure of a rice transplanter.

[Conventional technology]

As the conventional support structure, for example, as shown in FIG. 7, an insertion hole (22) in which an adjacent marker (15) can be inserted upright in the upper and lower portions near the opening end of the pipe frame (17).
The holding member (23) which is formed in the pipe frame (17) and through which the marker is inserted,
The structure is such that the marker (15) is clamped and held by moving it relative to the pipe frame (17) by tightening.

[Problems to be solved by the device]

The adjacent marker indicates an existing plant adjacent to the planting area in order to maintain a constant spacing between the existing plant and the planting plant when planting seedlings on a rice field with a large amount of water. , It is designed so that the operator can always proceed in the proper position.

However, in the above-mentioned conventional structure, since it is a screw tightening structure, for example, when the marker is prevented from contacting with a foreign substance and damaged when traveling on the road surface, or when the marker is avoided upward, or when the marker is turning, In order to avoid contact between the ridge and the ridge, the screw loosening work and the tightening work must be carried out each time, which is a troublesome work.

An object of the present invention is to effectively utilize a cap member that is necessary to prevent intrusion of muddy water into a pipe frame, thereby adjoining a rice transplanter with improved workability without inviting a complicated structure. The point is to provide a marker support structure.

[Means for Solving the Problems]

A feature of the present invention is that a cap member made of an elastic material is fitted into an opening end of a pipe-shaped frame protruding laterally outward from the machine body to seal the opening end of the pipe-shaped frame and An adjacent marker indicating an existing plant is provided in a state of vertically penetrating the pipe-shaped frame and the elastic cap member, and the elastic cap member elastically holds the adjacent marker so that the vertical displacement can be adjusted. It has the following features and effects.

[Action]

That is, at the opening end of the pipe-shaped frame, the cap member seals the opening in a tight contact state by its elastic reaction force to prevent intrusion of muddy water and the like, and moves the adjacent marker up and down according to the work situation. In this case, the adjacent marker may be pulled up or down against the elastic holding force of the cap member, which can be easily performed without the need to perform a troublesome screw tightening work as in the conventional structure.

[Effect of device]

Therefore, according to the present invention, the member for projecting a cantilever on the lateral side of the machine body in a cantilevered manner and effectively utilizing the member for sealing the opening of the frame, which is formed in the shape of a pipe to secure the strength, is provided. It has become possible to provide a device that can easily perform the vertical adjustment work of the adjacent marker without causing complication.

Moreover, the cap member for sealing the open end of the pipe-shaped frame is fitted into the pipe-shaped frame, and the adjacent marker is provided so as to vertically penetrate the pipe-shaped frame and the cap member, thereby supporting the marker. And there is an advantage that the cap member can be securely prevented from coming off.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 shows a riding type rice transplanter according to the present invention. This rice transplanter is constructed by connecting a seedling planting device (2) to the rear part of the riding type traveling body (1) so as to be able to move up and down.

As shown in FIG. 3, the seedling planting device (2) is provided with a fertilizer applying device (3) that can embed a fast-acting fertilizer and a slow-acting fertilizer at the same time when planting the seedlings.

In other words, the fertilizer application device (3) has a downflow front pipe (5a) for down-flow guiding the fast-acting fertilizer in the lower front part of the feeding mechanism (4) and a down-flow pipe guiding the slow-acting fertilizer down the rear part. The pipe (5b) is extended in communication.

A plate-shaped grooving device (6) that makes a relatively shallow groove on the mud surface is provided at the lower end of the front side downflow pipe (5a), and a deep groove is made at the front part of the backside downflow pipe (5b). A rotary grooving mechanism (7) is provided. This rotary grooving mechanism (7)
The transmission case (8) that also serves as a support frame is supported by an extended support case (9) fixed from the rear end of the transmission case (8), and the bevel gear (12) is transmitted from the drive horizontal shaft (11) of the planting mechanism (10). It is configured to include a plurality of excavation claws (14) that are rotated by being supplied with rotational power through a shaft (13). This ditching mechanism (7) has a thin mud surface and is configured to be able to bury the slow-acting fertilizer at a predetermined depth even when the fertilizer-embedded portion is a cultivator. .

And even if there is a lot of water in this rice transplanter,
Adjacent markers (15) are provided for performing planting work while keeping the spacing between planting strips constant. In other words, if the aircraft is operated to maintain the state in which the adjacent marker (15) is supported along the existing plant adjacent to the work area for planting, a certain interval can be secured.

Next, the support structure of the adjacent marker (15) will be described.

The adjacent marker (15) is a control section (16) in the traveling aircraft.
It is mounted in an upright position on the front end of a pipe-shaped frame (17) projecting laterally outward from both front parts of the.

That is, the adjacent marker (15) is elastically held in a vertical position so that the vertical displacement can be adjusted in the cap member (18) made of an elastic material such as rubber for sealing the opening end of the frame (17).

More specifically, as shown in FIG. 1, the cap member (18) is fitted into the pipe frame (17) in a close contact state, and a fitting tubular portion (for fixing the position by elastic reaction force thereof) ( 18a), the small-diameter tubular portion (18a) inside the fitting tubular portion (18a).
b) and a positioning step portion (18c) at the outer end, and the adjacent marker (15) is arranged in a state of vertically penetrating the pipe frame (17) and the small diameter tubular portion (18b).

As shown in FIG. 2, the marker through holes (19), (19) formed in the pipe frame (17) are formed as long holes along the longitudinal direction of the machine body, and the adjacent marker (15) has a small diameter. It is press-fitted so as to be elastically held in the tubular portion (18b).

With the above configuration, when the adjacent marker (15) is adjusted up and down according to the work situation, the operator is adjacent to either the upper or lower side against the elastic holding force of the cap member (18). This can be dealt with by pulling the marker (15), and the work can be performed extremely easily.

Moreover, in the above structure, when the lower part of the adjacent marker (15) contacts the ridges and the like, and the force in the direction opposite to the machine body advancing direction acts, the small diameter tubular part (18b) is elastically twisted. By moving, the adjacent marker (15) can avoid swinging in the longitudinal direction of the through holes (19), (19), and also has a buffering effect of preventing damage. Also, the longitudinal ends of the through holes (19) and (19) restrict the large swing, and the fitting tubular portion (18a) of the cap member (18) rotates with respect to the pipe frame (17). Thus, it is possible to prevent the set posture of the adjacent marker (15) from tilting back and forth. In addition, a seal portion (20) that contacts the inner surface of the frame (17) is formed inside the cap member (18) to the extent that it does not hinder the twisting rotation of the small diameter tubular portion (18b), and the through hole (19) is formed. ), (19) to prevent the intrusion of muddy water.

[Exemplary embodiment] As shown in FIG. 5, a constricted portion (2) having a smaller diameter is formed at an intermediate portion of the small-diameter tubular portion (18b) of the cap member (18).
1) may be formed to improve the cushioning effect.
